The invention relates to an anti-collision buffer structure, a side brush device and cleaning equipment. A floating disc of the anti-collision buffer structure is arranged below a fixed disc and is not in direct rigid connection with the fixed disc; the touch electronic switch is annular and sleeves the periphery of the floating disc; the elastic pieces are distributed in the circumferential direction of the fixed disc at equal intervals, and the floating disc elastically abuts against the lower surface of the fixed disc through the elastic pieces. The floating disc elastically abuts against the fixed disc, and therefore the floating disc can deflect relative to the fixed disc in the oblique collision process, and the collision coping capacity of the floating disc is all-directional. When the floating disc is collided from any direction, collision force causes deformation of the elastic piece at the corresponding position, the floating disc generates displacement to absorb impact energy, and meanwhile the touch electronic switch detects collision and outputs a collision signal. And after the collision force is relieved, symmetrical elastic force generated by the elastic pieces distributed at equal intervals in the circumferential direction jointly acts to drive the floating disc to reset to the initial state of being centered with the fixed disc, so that rigid collision damage is avoided, and the structural stability is kept.

This application provides a method for manufacturing a display panel, a display panel, and a display device. The display panel includes: an array substrate; an isolation layer located on one side of the array substrate, including a first isolation structure and a second isolation structure; a light-emitting functional layer; a first encapsulation layer, the first encapsulation layer including a first portion located on the side of the light-emitting functional layer opposite to the array substrate and a second portion connected to the first portion and located on the side of the isolation structure opposite to the array substrate; a second encapsulation layer, the second encapsulation layer including a third portion and a fourth portion, the third portion located on a first surface of the first isolation structure, and the fourth portion located on a second surface of the second isolation structure. The third portion and the second portion at least partially overlap in a direction perpendicular to the plane of the array substrate, and a gap exists between the second portion and the third portion in the same direction. This improves the reliability of the encapsulation and enhances the performance of the display panel.

The invention discloses an adjustable anti-splashing welding protection device. The adjustable anti-splashing welding protection device comprises square protection glass and a welding handle connecting module. One side of the square protective glass is arranged at the front end of the welding handle connecting module in a clamped mode through a glass chuck, the welding handle connecting module comprises an angle-adjustable assembly and a welding handle fixing clamping jaw, and the welding handle fixing clamping jaw is used for clamping and fixing a welding handle. The angle-adjustable assembly is formed by connecting a multi-section connecting rod and a plurality of damping rotating shafts in series, the directions of the rotating axes of the adjacent damping rotating shafts are different, and the damping rotating shafts have a self-locking function, so that the square protective glass can be subjected to position and angle adjustment in a three-dimensional space and is kept stable after adjustment. The square protective glass is made of high-temperature-resistant borosilicate glass, and at least one surface of the square protective glass is provided with a plurality of light filtering coatings. The protection device and the welding handle are integrally connected, so that cooperation of protection and operation in the welding operation process is achieved, and the safety and adaptability of welding operation are improved.
